Low-concentration PCB analysis


From the range of analysis methods at our disposal, we select the most appropriate one for rapid and accurate analysis.

From sampling to analysis


Analysts from Ohno Associates’ Institute of Environmental Science and Technology (Ohno Labo) visit the site to collect samples. We can also send sampling kits to customers for them to take samples themselves, which they can then send to Ohno Labo.


At Ohno Labo, we use two types of simplified quantitative methods and one rapid determination method to conduct efficient and reliable analysis at an affordable price.

※N.B.: The time taken to report the results depends on the size of the sample.
